Design Pattern and ABAP Objects
Hello Friends,
I would like to know, if ABAP Objects can be used to do pattern oriented programming ?
For example GANG of four has provided almost more then 30 design pattern ( MVC, singelton, Obserable, FACADE,,,etc) can we implement patterns using ABAP ??
Many thanks
Haider Syed
Hi,
Take a look at the following site:
http://patternshare.org/
It has all the basic patterns from the GOF and a lot more. I can recommend the ones from Martin Fowler but be sure you start with the ones from the GOF.
All patterns are described by using UML so it's very easy to translate them into ABAP OO code.
Regarding your other question. For the observer pattern I used an interface which the SAP had already created if_cm_observer and created my own abstract observable class. The observable class is nearly a 100% copy of the java.util. one

Design Patterns in ABAP.
Hi,
I want to know about the Design Patterns in ABAP.
Regards,
Souravhi sourdi
Below are the list of Design pattern in abap .
Singleton: ensuring single class instantiation
Adapter: making class interfaces compatible
Factory: encapsulating object creation
MVC: decoupling business logic from the view
Facade: providing a simplified interface
Composite: treating individual objects and compositions uniformly
Decorator: forming a dynamic chain of components to be used as one by the client

Object Oriented prg
A programming technique in which solutions reflect real world objects
What are objects ?
An object is an instantiation of a class. E.g. If Animal is a class, A cat
can be an object of that class .
With respect to code, Object refers to a set of services ( methods /
attributes ) and can contain data
What are classes ?
A class defines the properties of an object. A class can be instantiated
as many number of times
Advantages of Object Orientated approach
Easier to understand when the system is complex
Easy to make changes
Encapsulation - Can restrict the visibility of the data ( Restrict the access to the data )
Polymorphism - Identically named methods behave differently in different classes
Inheritance - You can use an existing class to define a new class
Polymorphism and inheritance lead to code reuse

How to implement Strategy pattern in ABAP Objects?
Hello,
I have a problem where I need to implement different algorithms, depending on the type of input. Example: I have to calculate a Present Value, sometimes with payments in advance, sometimes payment in arrear.
From documentation and to enhance my ABAP Objects skills, I would like to implement the strategy pattern. It sounds the right solution for the problem.
Hence I need some help in implementing this pattern in OO. I have some basic OO skills, but still learning.
Has somebody already implemented this pattern in ABAP OO and can give me some input. Or is there any documentation how to implement it?
Thanks and regards,

Which Design Pattern and how to design using OOP this scenario
I am having trouble designing a module, can anybody help me?
Because it will be hard to maintain this kind of module, I also think that this can test my skill of design pattern usage.
Requirement
This is basically an agricultural project (web application). I need to design a module where some calculation takes place.
There are different crops involved like maize, tomato, okra etc. Each of these crops has different traits.
Each trait has a measurement scale which lies in integer like 200-1000. Now let's say I have planted the crop and done measurement noted down the traits. Now I want to do some sort of measurement. Some measurements are simple and some are complex.
Example
Lets take an example of crop maize. I have recorded observations for 15 traits. (We'll use trait1-trait15 as examples, the actual name can be like plt_ht, yld, etc.)
I recorded 5 observations for each trait:
trait1 trait2 trait3 trait5 trait6..... trait15
01,02,03,04 01,02,03,04 01,02,03,04
User logs into system and selects his crops and enters data for these observations. I have to calculate either average or sum of the data entered for each trait.
Complexity / centre of the problem
So far it's simple but complexity comes when I have some different formulas for some of the traits.
Example: trait YLD has a formula based on which I have to calculate its value, which may also depend on some other traits. Each different crop can have different traits.
All this I am able to do - whenever user selects crop I will check for those specific traits and do calculations (if it's not a special trait then I either average or sum it, based on db entry), but there is a lot of hard coding.
I would like to have suggestions on a better way of handling this.
My code needs to handle both simple and complex calculations.
Simple calculations are easy, I have take average of value entered for trait.
The problem comes when I have to do complex calculations, since each crop have different traits with their own formulas, so to calculate I have to check for crop and then for complex trait. So I have to hardcode the trait name of complex traits.
Can any tell me how I can design this using Java oops [?!?] so that I can make it generic?
I have about 10 different crops. Some calculations are specific to crops, so there will be lot of code like the if below:
hasZeroValue = (HashMap<String, ArrayList<String>>) dataValues[1];
} else if(cropId.equalsIgnoreCase("MZ") && traitName.equalsIgnoreCase("Shelling")) {
avg=HybridTestDataUtility.calculateAvg(traitName, dataPoint, dataTraits, traitValues,dataPvalues, dataPoint, type);
avg=avg*dataPoint;
traitAvg=getMaizeYeild(traitName, traitAvg, population, avg, hybrid, area);
} else if(cropId.equalsIgnoreCase("OK") && traitName.equalsIgnoreCase("YLDGM")) {
avg=HybridTestDataUtility.calculateAvg(traitName, dataPoint, dataTraits, traitValues,dataPvalues, dataPoint, type);
//avg=avg*dataPoint;
Object[] dataValues=getOKRAYield(traitName, traitAvg, population, avg, dividend,hasZeroValue,hybrid,repl);
traitAvg = (HashMap<String, Float>) dataValues[0];
hasZeroValue = (HashMap<String, ArrayList<String>>) dataValues[1];
} else if(cropId.equalsIgnoreCase("HP") && traitName.equalsIgnoreCase("w1-w10")) {
avg=HybridTestDataUtility.calculateAvg(traitName, dataPts, dataTraits, traitValues,dataPvalues, dataPoint, type);
avg=avg*dataPoint;
Object[] dataValues=getHotPepperYield(traitName, traitAvg, population, avg,dividend,hasZeroValue,hybrid,repl);
traitAvg = (HashMap<String, Float>) dataValues[0];
hasZeroValue = (HashMap<String, ArrayList<String>>) dataValues[1];
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("TLSSG_70")) {
traitAvg=calculateTLCV(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues,50);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("TLSSG_100")) {
traitAvg=calculateTLCV(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues,50);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("YVMV_60")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("YVMV_90")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("YVMV_120")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("ELCV_60")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("ELCV_90")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("TO") && traitName.equalsIgnoreCase("ELCV_120")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg,dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);

} else if(cropId.equalsIgnoreCase("OK") && traitName.equalsIgnoreCase("YVMV_120")) {
traitAvg=tomatoYVMVCalculation(traitName, traitAvg, dataPoint, dataTraits, hybrid, repl, traitValues, dataPvalues);
} else if(cropId.equalsIgnoreCase("OK") && traitName.equalsIgnoreCase("ELCV_60")) {Can anybody think of a way to make a generic approach to this?There are crops and each crop have traits , traits are actually a mesuremet
scale to decide growth of a seed of a particular crop.
This module is to for planters to observe growth of seeds sowed of certain
crops and take down n no of observation for each trait and upload in csv format.Once they enter
data i have to either avg out the values or sum the values or sometimes
there are more complex function that i have to apply it may differe for each
trait .This is the whole module about.Just to give an idea about how they
will enter data
Hyubrid(seed) trait1 trait2 trait3 trait5 trait6..... trait15
Hybrid1 01 02 03 04 01
HYbrid2 04 06 08 04 01
HYbrid2 04 06 08 04 01
HYbrid2 04 06 08 04 01
HYbrid2 04 06 08 04 01
Once they enter data in this format i have to give result something like
this.
Here avg colum does not necessaryly mean avg it can be sum or any formula
based resutl.Hybrid is the seed for which they record the observation.
I have shown avg column only for two tratis it is actually for all the
traits.
Hyubrid(seed) trait1 Avg trait2 avg trait3 trait5 trait6..... trait15
Hybrid1 01 01 02 04 03 04 01
HYbrid2 04 04 06 10 08 04 01
HYbrid2 04 04 06 12 08 04 01
HYbrid2 04 04 06 14 08 04 01
HYbrid2 04 04 06 12 08 04 01
Hope this clarifies atleat a but
The data are not correctly indented but there is no way i can format it. -
Hi all,
I'm trying to use ABAP Objects with smartforms. The thing is that whenever I need to display an object attribute, I have to call a getter method (say object->getSomeAttribute for example), assign the return to a global variable in the smartform, then assign that variable to the text node. I would like to know if there is a way to avoid this and do like we usually would do for field in a structure, i.e. assign sommeStrucutre-someField directly to a text node without using a global variable. Thank you in advance.Hi,

Data Lista Handler Design Pattern and paging queries
I'm using Toplink in an MVC (Regular Beans, JSP and Struts) application. I'm not using ADF. At least not until i make up my mind on the features-portability tradeoff.
Anyway, my application will have to use queries to show the data to the user. This can easily be accomplished by putting the search parameters on my jsp and using ReadAllQuery to compose my query.
My problem is that the result can return a large amount of records and show all this records at once on the jsp might take a time the user won't be willing to wait. That's when paging the results will come handy.
In another application of mine i use paging manipulating the rownum of the query, but in that case, i had control of the whole sql statement. As this is the first time i'm working with Toplink, i'm feeling that can't be done.
There's the Data List Handler design pattern too, but that one also manipulates the sql statement.
I'm wondering now whether paging can be accomplished using Toplink..? Will i have to use ADF...? This kind of stuff.
Thanks a lot to all.
- EduardoEduardo,
What you need to do is use Cursors in TopLink.Scrollable cursors enable you to scroll through a result set from the database without reading the whole result set in a single database read. The ScrollableCursor class implements the Java ListIterator interface to allow for direct and relative access within the stream. Scrollable cursors also enable you to scroll forward and backward through the stream.
Here is an example:
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(Employee.class);
query.useScrollableCursor();
ScrollableCursor cursor = (ScrollableCursor) session.executeQuery(query);
while (cursor.hasNext()) {
System.out.println(cursor.next().toString());
cursor.close();
I hope this answers your question.
Deepak -
Hey,
I do wanna know if is recommendable to use a Java Design Pattern (like Singleton, Fa�ade, etc)... in a J2ME application. I mean, a colleague of mine made a j2me application using these kind of technologies, but, when he installed in his cell phone, the application occuppied much memory. So, another guy told me that due to the limited memory space we find on these devices it's better for us to use only the MVC idea. So, is it recommendable for me to use this kind of resources???
Thanks!Hi,
it is a good programming practice to use Design patterns. But too much of design patterns results in more classes which will be a problem in j2me sometimes.
Most of the MIDP classes uses Singleton and abstract design patterns -
String.matches vs Pattern and Matcher object
Hi,
I was trying to match some regex using String.matches but for me it is not working (probably I am not using it the way it should be used).
Here is a simple example:
/* This does not work */
String patternStr = "a";
String inputStr = "abc";
if(inputStr.matches( "a" ))
System.out.println("String matched");
/* This works */
Pattern p = Pattern.compile( "a" );
Matcher m = p.matcher( "abc" );
boolean found = false;
while(m.find())
System.out.println("Matched using Pattern and Matcher");
found = true;
if(!found)
System.out.println("Not matching with Pattern and Matcher");
Am I not matches method of String class properly?
Please throw some lights on this.
Thank you.String.matches looks at the whole string.
bsh % "abc".matches("a");
<false>
bsh % "abc".matches("a.*");
<true> -
First try with ALV Grid and Abap Objects
Hi,
this is my first try to write a simple report which just reads a textfile and display it in an ALV Grid. As a basis, I used some examples from SDN, but it did not work as expected
I would like just to use a docking container. I do not need a separate area for the ALV Grid. The report gives no syntax errors, but it just display the report title, nothing else. SAP R/3 Release is 4.7. Below is the source code of the report. Any idea what is missing?

ENDFORM. "build_fieldcatalogI have added some more functionality to my report. The good thing is, the report works as it should.
BUT, I'm not really sure, whether this is a good (correct) design. The report works the following way:
1. Read planning data form text file into internal table
2. Display the internal table
3. Convert the data and display the converted result
4. Post the converted data to the system
5. Display log with messages
The main thing is, I would like to know, do i really need two dynros, to display the two different internal tables or is it possible just to use one ALV-Grid? I was not able to find another solution. Any comment or help to the report is appreciated.

Screens and ABAP Objects - R/3 4.6c
Greetings fellow SAP developers.
Looking for some input here. What's the best way to manage dialog screens with ABAP OO?
Do you encapsulate the screen in an object? So that there is just one method or two methods? As in:
Screen->Init
Or do you break it down into chunks? As in:
Screen->Set_Fields
Screen->Validate
Screen->Handle_Action
Or do you avoid using objects to encapsulate screens? That is, just use objects to encapsulate business processes? As in:
SCREEN_FIELD_1 = BusinessObject->Get_Value_1()
SCREEN_FIELD_2 = BusinessObject->Get_Value_2()
Thanks in advance for your input.
BrettSure you can handle PBO and PAI of screen using objects, take a look at transaction MIGO, its full of it. The only thing is is that you can not use the "CALL SCREEN" statement inside your objects.
Regards,
Rich Heilman -
Get instance method and design pattern
Hi All,
1. I New to abap objects and i read the help and some stuff from the forum,
l like to now more about design pattern in abap objects,
2. I saw in some abap class the use of method of GET_INSTANCE i think it's from factory pattern , what is the pros. and cons to use this method ,when i should consider to use it ?

A very good introduction into design patterns is the book "Head First: Design Patterns". Here you will find many good reasons why and when to use the factory pattern.
You should use the factory pattern when
- you want to prevent "direct" instantiation (i.e. using a public CONSTRUCTOR method) by the developer
- you want to hide the complexity of instantiation from the user of the class
- the instantiation creates an implementation of an interface and you want to keep control of which implementing class is returned
